iTunes U: Thanks for the comment. There is some hessitation around the state to get behind iTunes U (as there should be), but our goal is to take advantage of the popularity of the iTunes syndication engine to build awareness of educational technology in Michigan.
With your interest in Education Technology, I recommend you take a look at Wiziq's virtual classroom and authorstream's power point presentation platform. Both are web based platforms, have a bunch of features and free basic service. Here’s a public class recording you might find of interest.
